The first driving portion 160 and the second driving portion 170 receive an instruction and cause the first moving frame 121 and the second moving frame 131 to first move laterally to a predetermined position, and then the jacking driving unit 184 receives the instruction and causes the lifting frame 106 to rise to a predetermined position. Position, at this time, the first fork 122 forks the lock base of the vehicle 200 for locking the battery pack, the second fork 134 forks the battery of the vehicle 200, and the unlocking mechanism 123 unlocks the battery lock so that the battery is no longer locked to the vehicle 200. Then, the first moving frame 121 remains stationary, and the second moving frame 131 moves in a direction away from the first moving frame 121 to cause the battery to be detached from the vehicle 200, the battery is detached from the vehicle 200, and then falls onto the tray 133, and then the frame is lifted. The 106 is moved down, with the battery moving down, and then the first shuttle 318 is driven away from the bottom of the vehicle 200 with the removed battery.

When the battery of the vehicle 200 needs to be installed, the first shuttle 318 moves to the bottom of the vehicle 200 with the fully charged battery, and the first driving portion 160 and the second driving portion 170 receive an instruction and cause the first moving frame 121 and the second movement. The frame 131 is first moved laterally to a predetermined position, and the jacking drive unit 184 receives an instruction and causes the lift frame 106 to rise to a predetermined position, at which time the first fork 122 forks the lock base on the vehicle 200 for locking the battery pack, the second The fork 134 forks the fully charged battery, then, the first moving frame 121 remains stationary, and the second moving frame 131 moves toward the first moving frame 121 to fix the battery to the vehicle 200 and the unlocking mechanism 123 to the battery Locked onto the vehicle 200.

As shown in FIG. 15, the power substation 300 includes a charging chamber (not shown), a power exchange platform 190, a lifting mechanism 191, and a first shuttle 318.

The lifting mechanism 191 is disposed on the power exchange platform 190 and is used to lift and lower the vehicle 200 on the power conversion platform 190. The lifting mechanism 191 is generally a block for supporting the four wheels of the vehicle 200. In Fig. 15, the elevating mechanism 191 is in a raised state.

The first shuttle 318 can travel between the power exchange platform 190 and the charging chamber for transporting the fully charged battery 210 in the charging chamber to the vehicle 200 or transporting the battery 210 removed from the vehicle 200 to the charging chamber for charging. .

When the first shuttle 318 is loaded with the battery 210 (whether the battery removed from the vehicle 200 or the fully charged battery) and needs to be moved in and out from the bottom of the vehicle 200, the lifting mechanism 191 lifts the vehicle 200 upward to The first shuttle 318 is allowed to smoothly enter and exit the bottom of the vehicle 200.

Since the first shuttle 318 employs a cam mechanism, its own height is low (the total height of the device is 175 mm), the four cams 181 are lifted by 80 mm in synchronization, and the height of the floor of the vehicle 200 from the ground is generally 190 mm. After the vehicle 200 enters the power exchange platform 190, the first shuttle 318 can directly enter the bottom of the vehicle 200, and the first shuttle 318 lifts 80 mm to achieve locking or unlocking of the battery. After the battery is removed, the lift mechanism 191 raises the vehicle 200 by 200 mm to allow the first shuttle 318 to be removed from the bottom of the vehicle 200 with the battery.

Since the overall height of the first shuttle 318 is reduced, the power exchange platform 190 of the power substation 300 does not need to be provided with deeper dimples to allow the first shuttle 318 to enter the bottom of the vehicle 200, thus the overall height of the power exchange platform 190 The height of the upper ramp 304 and the downhill 305 that enters the power exchange platform 190 can be reduced to 230 mm (the original height is 480 mm), and further, thereby reducing the difficulty of driving the vehicle 200. The lengths of the upper ramp 304 and the lower ramp 305 are also correspondingly reduced, from the original 7345 mm, 4545 mm to 4500 mm, 3000 mm, thereby reducing the construction cost of the substation 300.
